The presentation shows the impact of different meshing strategies on the simulation of the in-cylinder flow structure of the Transparent Combustion Chamber (TCC) engine. Large Eddy Simulation of several consecutive engine cycles are compared to experimental measurements, and the impact of the adopted meshing trategy on both accuracy and computational efficiency is evaluated.

Cylinder head temperatures are critical for understanding engine performance and durability. Accurate predictions of head temperatures are difficult due to the amount of physics interacting with the head. These interactions such as heat release due to combustion, valve heat transfer and friction, internal and external cooling, and oil splash cooling all contribute to head temperatures. To predict head temperature, a conjugate heat transfer (CHT) analysis integrating all of the interactions was performed.
